Abstract

A gate leakage insensitive current mirror circuit (100) including an input stage (110), an output stage (120), and a pair of complementary source followers (130). The pair of complementary source followers is connected between the input stage and the output stage. In operation, the input stage receives an input current and the pair of complementary source followers receives a first current source and a second current source. The output stage then provides an output current. The complementary source followers form a negative feedback loop and establish a bias voltage for the input stage and the output stage as a function of the input current that is independent of gate leakage between the input stage and the output stage.
